Comprehensive DC breakdown for all classes

[Qezuzu]

This will break down the DC for every class and school (that matters). It makes some assumptions:
-Character is going for maximum DC's in that specific school. If you are not, reduce appropriately.
-Character is in the destiny which would provide maximum DC's. For WIS/CHA-casters this is Exalted Angel, and for INT-casters it is Magister/Draconic.

And some omissions:
-No unsustainable or unreliable buffs such as House D pots, Bard Songs (unless the caster is a bard), cookies, Joy of the Queen, etc.
-No Archmage wizard. I don't believe they actually gain any DC over Palemaster due to Lich-form and Harper Agent
-No multiclasses. Yes some builds can have slightly higher DC's, like 17Drd/3Brd or Monk Splash FvS, but that's just too complicated if we're trying to be comprehensive. Figure those builds out for yourself.

All sources of stat/DC are available in this spreadsheet. I encourage everyone to point out any mistakes I have made or things I have forgotten. I'm sure there's some, but I believe the errors are limited.

HERE IS THE SPREADSHEET FOR ALL MAXIMUM CASTER DC'S AT ALL LEVELS.

This image provides at-a-glance maximum DCs at a variety of levels.

Additional sources of DC:
All casters can benefit from Epic Deific Diadem, for +2 to all DC's. But, it interacts with different classes differently. Pale Masters can easily keep the bonus at +2 with Death Aura ticks, but a Druid who casts, say, Earthquake and then Storm of Vengeance, what bonus they have will be impossible to predict. Consider at your own discretion. Furthermore, it conflicts with a Reaper bonus hat, unless you have crazy luck and get a Reaper version of the Diadem.

Assuming two Epic feats are reserved for Epic Spell Focus and Embolden spell, Epic Stat and Stat Twists can give up to +7 to one stat. However, you will probably spend most of those points in other areas (e.g. Evocation/Conurjuation casters already have a twist reserved for tier2 Draconic). For ballpark figures, Wizard can normally afford +4 INT from these sources, and other classes will get +2 or +3 to their stats.

LGS tier3 gives +2 Exceptional to a stat, resulting in +1 over Globe of Blood, which could give +1 all DCs if this bumps you to an even score.

All casters, except Bard where it is already counted, can get +2 to DC's with Inspire Excellence and Spell Song Trance from a Bardic party member.

Arcane Archer tree comes with +4 to Enchantment DC's. Only Wizard has access to this though, through the Sun Elf AA tree. I don't know if there are enough points to invest very far into it.

Debuffs:
Not a complete list, but these are some useful ones.

No-save, AoE abilities:

-With Aura of Menace, FvS get effectively +2 to all DC's, passively, making up the difference between them and Cleric.
-With Mantle of the Icy Soul, Druid effectively gets +4 to DC's that target Fort and Ref on anything hit by their Cold spells.
-Druids also get Autumnal Susurrus, giving their Acid, Electric, and Negative spells a 40% chance to apply the shaken condition, which is -2 to saves. Storm of Vengeance and Call Lightning Storm are notable two AoE spells that can trigger it.
-By stacking Solid Fog and Waves of Exhaustion, Wiz and Sorc can debuff reflex saves by 7.
-Crushing Despair reduces will save by 5, even if mob makes it saves. Other spells like Hypnotism have a similar effect
-Bard's Insult from Swashbuckler reduces saves of a choice by 3
-Warlock's Taint the Blood from Soul Eater reduces fort saves by 4, after attacking a mob four times

No-save, single-target abilities;

-Exalted Angel's Shadows Upon You can provide up to -12 to saves. SUY -> Wizard PL Magic Missiles -> Finger/Destruct is efficient
-Magister's Spell School Augment gives 15% chance for Conj/Evoc | Enchant/Illu | Necro/Trans spells to lower Ref | Will | Fort saves by 5
-Energy Drain effectively gives -4d4 to saves. Enervation 2d4.

Save-based, AoE abilities:
-Crushing Despair gives another -2 if a mob fails its save against it
-Symbol of Pain gives -4 to saves if a mob fails its save against it
-Mind Fog gives -10 will saves if a mob fails its save against it

Save-based, single-target abilities:
-Inflict Curse gives -4 to saves

Secondary schools/build variance:
It is not possible to get these DC's in two schools at once. A secondary school will have a much lower DC. Furthermore, you may have to invest at least a little bit into spell pen, which could lower your DC's.

If you are not maxing a school, you will lose up to:
-3 from Magister tier2
-3 from 3x Spell Focus feats
-2 from appropriate legendary feat
-2 additionally if you do not have any of Scion of Earth, Air, Feywild, or Shadowfell

-3 for Illusion, if you use a race other than Gnome/Deep Gnome
-3 for CHA Evocation casters if they are not Dragonborn
-2 for Evo/Conj, from Draconic tier2
-1 for Enchantment, Bard PL feat
-1 additionally from Enchant if you're saving AP from racial Drow/Sun Elf tree

You will also lose more if your class provides DC through a multi-selector, such as cleric (who must choose +2 necro, +2 evoc, or +1 each).

It's also entirely possible that you will not be able to fit in all the DC-boosting equipment for a secondary school, or you will do something like not wear Thunderforged armor in favor of something that gives bonuses in other areas.

Obviously these all depend on your personal build choices. Also I assume a +7 tome which many people don't have. +5 is readily obtainable, though grindy, through 5k favor reward.

DC boosts:
For WIS/CHA casters, Exalted Angel's Ascendance ability gives an unlisted +2 to WIS and CHA, for +1 to DC's. Ascendance lasts two minutes and has a five minute cooldown, a respectable 40% uptime.

Arcane Insight gives +6 to DC's for 30 seconds. Three minute cooldown.

Magister can boost DC's by +5 for 20 seconds, but this only applies to INT casters. Five minute cooldown.

For Warlocks, the first core in Tainted Scholar gives +2 DC's for 20 seconds. One minute cooldown.

Harper Agent Tier5 has a passive +1 to all DC's, and also comes with 10 seconds of +10 to DC's. But it has a five minute cooldown, and conflicts with class trees.

Furry of the Wild's Acute Instincts gives +2 WIS, but requires drinking a Rage potion. This boost can be sustained indefinitely. It is already counted in the spreadsheet.

thanks for that list mate, really appreciate the effort. +1

Could you please make download available? Thanks!

I don't believe that option has been disabled.

Added spell pen breakdown.

I was wrong in the breakdown for CHA. You can't take +2 CHA from harper, +2 racial CHA, +2/capstone from your main tree and then +1 from a secondary class tree, but you are able to take +2 CHA from a second class tree and only 7 AP for +1 CHA from harper. Final CHA score is unchanged. Warlock notably gets +1 Ench/Necro/Illu DC from this as there was a +1 DC's to those in Soul Eater that I missed.

Wizard can also do stuff in Archmage and take some INT out of Harper, but I don't think they gain a net increase to DC's. I'd like someone to verify.

Q,

Thanks for taking the time to put this together.

On the spreadsheet, I see 9 points of INT in the Stat Exclusive section. You Total out of the previous section at 73 INT and are ending with 84 INT. Am I missing a line or should this be a total of 82 INT? And then 90 INT for wizard at the end of that page?

You are correct, thanks for catching that.

Added a third table. This is maximum, typical DC's for each class, including Completionist, some stats twists, Diadem, debuffs, and all that good stuff.

Started non-caster category, with Assassinate DC.

Added Artificer. This includes the upcoming u30 tweaks. Max-DC is actually viable due to INT-to-damage and the number of feats they get.

[Qezuzu]

With the FvS debuff aura for -2 saves, Druid -6 saves from Mantle of Icy Soul and Susurrus, Bard songs for +2 DC's, Bard Insult for -3 saves, and Warlock Taint the Blood for -4 saves, and a max-Necro DC Wizard, a party of casters can reliably FoD one LE Shroud mob, provided they also use Energy Drain on it twice.

[PsychoBlonde]

I don't see you have the +2 wis on Acute Instincts (Fury of the Wild) when raged anywhere on here. Since it just requires drinking a rage pot, it's pretty nice.

[Ewynn]

+1 Very useful

...now, about those Ravenloft updates...

:-)

I'm working on a re-organization of how I display the breakdown.

I made this cruddy spreadsheet a couple years ago now and it's been alright, but I think it could be a lot better as far as usability goes. Ideally it would not be a hastily made spreadsheet.

Main things:
-"you can have an insight bonus of +2 to your DC at lvl 14" is very unhelpful information. "Skulled Ring from A Raven at the Door, or Cannith Crafting on Goggles/Ring/whateveritcanbeon, are your options for Insightful Necromancy at this level" is much better
-including bonuses like the default +2 every Enhancement tree gets, or what races what stat bonus, or that Destinies gives +6 to a stat by default, etc. is pointless to include. Anyone reasonably familiar with DDO knows this information and it clutters up the main information I want to display.
-includes all bonuses, and it's not very clear that it's ALL bonuses, minus some 'unreasonable' ones that I arbitrarily dictated were more unreasonable than taking all of focus/greater focus/epic focus/embolden/bard pl/wiz pl while using an alchemical weapon for an Enchantment-based cleric.

I'm thinking of things that can replace it, but whatever it is it would be some web interface where you input your class level and what school you're looking for bonuses for, and it would spit out a list of everything that can improve your DC and where it can be obtained.
